'fj" "Tqalltoiwm it may concern Be itknown that 1, l /IICHAEL 'S'raonnn, citizen of the United States, resid ng; at

NValkenin the county of Cass and Stateof Minnesota, have invented certain new and useful Improvements 1].1 Stump-Pullers, of

which the following is a specification.

1 This invention relates to stump pullers or extractors and more particularly to that type. wherein a weight is adjustably mounted upon a pivotally supported beam for gen-.

erating the lifting or. pulling power required inextractingpr removing stumps from the soil.

The primary object of-the invention contemplates the provision of an'adiustable' carrier-adapted to be slid throughout'the length ofthe pivoted beam for elevating.

'iandadjusting the-weight member carried stumps of various size to be extracted or rethereby, this arrangement permitting moved without altering or aifectingpthe construction of the device; other than ad- --is in condition to be transported or conveyed -justingfthe said carrier.

on resides A further object of the inventi in the provision of means whereby the said pivoted beam may be broken centrally so as to permitthatportion upon which the carrier is adjustably mounted, to be swung ordropped into engagement with the ground, in which-posit on the entire device by any suitable motive power from place to place.

, The invention stillffurtherwresides in the provision of a;.peciallvdevised carrier upon which 1 is, arranged agsuitable pawl adapted to engagezthe'teeth of a rack bar carried by the beam for locking the said carrier against'movement when proper ad- 7.

""justment thereof is accomplished.

The above andadditional objects are accomplished by such means as are illustrated a in their preferred embodiment 1n the accompanving drawings, described in the followme specification and then more particularly pointed out in the ClillHlSWlllCl'l are appended hereto and form a part of this application. V i

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views and in which I Flgure' '1 S. {LLSldB elevation of a device or-machine'constructed in accordancewith my invention Fig. 2 is a similar view, 'the .beam being swung into aninoperative position, the dotted lines illustrating the positlon of the beam during conveyance; Fig. 3 is'a top plan viewof the device; Fig.4 is'a longitudinal sectionaliview; Fig. 5 is an enlarged detail perspectiveyiewpf the carrier and Fig. 6 is a fragmentary view illustrating the manner. iniwhich the ra'ck bar is adiustably supported.

. "Referring now to the drawings wherein is illustratedthe preferred form of myinvention the numeral 1 designates .the main frame of the machine, the said frame being supported through the medium of wheels 2 arranged upon the mainaxle 3 of the machine. The. axle 3 is preferably rectangular in cross section. and has bolted thereto as at l a suitable bracket 5, thelatter'havin'g pivotally arranged thereupon the main beam 6' of the device, the pin 7 upon which the saidbeam is supported being remov'ably .in-

serted in an opening provided therefor within the said beam 6,'this construction permitting the beam to be removed from'the said axle should occasion demand. The rear end i of themainbeam 6 is provided with a central projection,8. the said proiection adapted to fit between the portions 9 of. the bifurcated end ofthe extended portion of the 7 said beam 10.; A pin 11 carried by the beam "6 by means of a chain12 is adapted to pass i through jalined openings 13 of the said prov the openings 13 provided therefor.

'An elongated opening or cutout portion 15 is formed in the extended portion 10 of the beam 6 the said opening extending throughout the 'major portion of the length thereof and having a sprocket chain 16'arranged therein oversprocket wheels 17 and "18 respectively mo nted at the forward and rear ends of the said opening. A gear wheel 19 is keyed or otherwise secured or mounted 'uponthe same shaft as the-sprocket Wheel 17, the said gear wheel being disposed upon .the exterior "of theJoeam'and adapted ..to

mesh intoa-large gear likewise arranged upon the exterior of the'beam adjacent the pivot point 14. The said gear 20 is provided with a crank handle 21 by means of which motion is imparted thereto where it is transmitted to the sprocket chain. 16 through the.

medium of'a small gear wheel 19 and the wheels 17 and 18 upon which the sprocket chain is arranged;

A carrier, designated in its entirety by the numeral 22 is slidably mounted upon the exthis construction imparting movement to the tended portion 10 of the beam, the said carrier having a wheel 23 rigidly mounted thereupon and provided with teeth, 24 against which the linksof the chain 16 abut,

7 carrier according to the movement :of ;the

chain, as the said wheel 23 being stationary,

and the teeth-thereof engaged by the sprocket chain sliding movement is impartedthereto. The body portion 25 of the carrier is preferably semicircular in form and is arranged over the extended portion 10 of the beam as is clearly shown in Fig.4 of thedrawings,

-the said body portion having an extension or,

depending portion 26 securely fastened thereto for the purpose of supportinga weight member 27.

Adj ustably mounted-1 upon the exterior of:

the beam 10 uponeach side thereof I provide a rack bar 28 one end of which is inclosedwithin a suitable housing 29 and attached thereto by means of an expansion spring 30 arranged. wlthinthe said housing. Ratchet teethBL-are formed upon the forward end ofthe rack bar-28 the said teeth meshing into a segmental; rack 32 carried by the beam 10, and movement being I imparted to the said rack by means of a hand 5 lever 33i sec ured'ito and depending there from. By operating or actuating the hand i lever 33 it will be seen that movement isimparted to the rackbar 28 this slight movement permitting minute adjustment a-of the carrier retaining mechanism to be hereinafter fully described.

Alever 34 ispirotally supported as at 35 over the carrier body portion 25, the said lever having a hook member 36 secured to one-end thereof adapted to engage a staple 37 of the carrier, the provisicn of which will prevent movement of the said lever when so desired. The opposite end of the lever 34 is connected to a bail 38, the said bail adapted to straddle the body portion 25 of the carrier v and have secured at each end a vertically slidable pawl 39, the latter being supported or retained in properplaceby means of slide-- ways 4-0 fastened :to the depending portion '26 of the carrier. The pawls 39 being arranged directly over the rack bars 38 of the beam. it will be seen that minute adjustment of the carrier is permitted and that the same is locked in'adjusted position upon the beam by reason of the eng g ment bet een the said pawls 39 and the teethof the rackhars 28, a the latter extending upon each side: of

the beam throughout: the length. of the: sprocket chain 16 arranged upon the interior;

of the opening 15'formed within the :said

beam. Guide-ways 4liare= also secured to' the depending portionz 26 of the carrier, the,

said guide-ways being disposed at right angles to the-guide-ways 40 and adapted; to form a support or rest for the rack' bars' 28;

which extend, therethrough thereby atrall times supporting the said rack bars in direct alinernent with the fpawlsl 3 9 above-men tioned.

Having described I the manner in; which,

the carrier is adjusted ;upon the beam por tion 10 it now remains to describethe manner in which the said beam portion is -ele-. vated or swung upon its pivot point, created] A*hookeby the main axle 3 of the machine.

shaped member 42 is formed integrally with f and upon the rear extremity of the extended portionlO of the beam,'the said member be: ing connected to a drum 43, revolubly mounted upontheimaini frame :1, byimeans, of a;- -rope 44 adapted to pass over a roller .45 ar-;

ranged between brackets 46 4 carried :by ;the 1 said mainframe. cured, upon the extremity of the drum "shaft or drum .43nthe said ratchet having .ahandle';

A ratchet wheel 4'7. lis'see 48 provided thereforby .means of which? ro--- tation is imparted to the drum 43, thns pen; 1 mitting, the rope 44 tobe'wound thereupon for elevating the extended portion; 10 of the beam.: To prevent junwindingof' the ratcheti 47 a {pawl :49 is" pivoted Tas at 50 upon the frame side 1 of the machine.

A supportingbracket 51 is secured to the 5 The forward extremity of the main beam 5 6 has formed integrally therewith 'apairof: f

spaced apart hook shaped members 52, thez said members adapted to the forced beneath the stump to be extracted in a manner :to be:

hereinafter fully described. I

Pawls 53 are pivoted as at 54 to the rear end of the main frame 1, the'said paw'ls;

adapted to engage the ground or soil to prevent backward movement of the device dur mg extraction Orstump; pulling operation,

hooks 55 being provided for supporting the said 1 pawls out of engagement with the grcund during. transportation or c0nvey ance of themachine.

A bracket 56 is secured to the rear end of the beam portion. 10 and is yie1dably,;sup-

ported ,by means of a spring 57 arranged:

beneath the hook shaped member 42 of the.

beam, this arrangement allowing the; said beams to be broken centrally or swung uponi its pi otle with ut engag ng or ontacting.

the-ground as the said bracket' 56 will yieldably support the said; beam .-vide. a ioushion' therefor.

which in turn elevates the hook-shaped member of :.the extendedportion' 10 of nthe beam. After swinging the; saiderr-V V tended portion into galinementwith-the main portion 6,;the pin llis insertedithrough the openings 13 provided there-for thereby efis then adjusted by means of the crank hanment of the sprocketuchain 16 which engages the. stationary toothedwheel23ofthe I carrier for adjusting the latter'throughout the lengthvof the said sprocket chain upon theextended portion 10 :ofthe'beam. After properly adjusting the/carrier as above set .forth'thehook36 is released from the staple'37 and'the pawlsi39 are freeto engage the teeth ofi therack bars :28 which engagement willsupport the said carrier in the desired adjusted position. Should a minute adjustment be required, operation of the handlet33 will "allowthe said rack bars to I slightly move by reason of the spring supports inclosed within thecasing-29v of the said rack-bars.

By. adjusting the -carrier-= as above described stumps; of various size maybe extracted'as the movement of thesaid carrier I toward the rear endof the beam portion 10 will cause the said beamtoswing upon its shaped. member52 and the stumpbeneath -connection with the accompanying drawings 4 that the beam may-be divided or broken centrally andvthe extendedportion 1O dragged ;over the ground during conveyance of the machine,-the bracket'56 forming a cushion therefor; that the said beam may be swung into alinement with the main portion 6 thereof by the manipulation or operation of the drum 43; and that the construction of the carrier, 22 is.-such asto permit adjustment thereof throughout theentire length of the; sprocket chain 1 6, toWhiCh it is atportion and pro- H whatl claim as new .Letters Patent,--.is: I
